Technically the top layer of permafrost, this is the active layer. IT can melt during the summer but refreeze during the winter. The lower layer is always frozen, however.

The layer above permafrost is known as the active layer. It is the top layer of soil that thaws and refreezes seasonally in response to changes in temperature. This layer plays a crucial role in supporting vegetation growth and allows for water movement in the soil.

What is an arctic plain with sub-layer of permafrost?
An arctic plain with a sub-layer of permafrost is a flat land area in the Arctic region where the ground underneath the surface layer remains permanently frozen. Permafrost is soil, sediment, or rock that stays below 0°C for at least two consecutive years, influencing the landscape and ecosystem of the area.
What is a sentence with the word permafrost?

What is permafrost on Mars?
Permafrost on Mars refers to a layer of soil or ice that remains frozen throughout the year. This permafrost is found in the polar regions of Mars. Studying permafrost can provide insights into the planet's past climate and potential for supporting life.
What is the difference between global climate changes and permafrost layer?
Global climate change refers to long-term changes in the Earth's climate system, including temperature, precipitation patterns, and sea level rise. Permafrost, on the other hand, refers to a layer of soil or rock that remains frozen for at least two consecutive years. Global climate change can lead to the thawing of permafrost, which can release stored carbon and methane into the atmosphere, exacerbating climate change.

How does grass covers a layer of permafrost?
Grass helps insulate permafrost by trapping snow on top of it, creating a thick layer of insulation that reduces heat transfer from the atmosphere. The grass also helps stabilize soil moisture levels, preventing rapid thawing of permafrost. Overall, the presence of grass on permafrost plays a crucial role in maintaining the frozen state of the permafrost layer.

What lies beneath the topsoil of the tundra?
Below the topsoil of the tundra is the permafrost layer, which consists of permanently frozen soil, rocks, and sediments. This layer acts as a barrier to water drainage and plant root growth. Beneath the permafrost layer is the unfrozen ground, which can include roots, soil, and debris.
